CHARLES F. BUENT, OF AVALON, PENNSYLVANIA.

PIPE-JOINT.

T0 all 'whom t may concern.'

Be it known that T, CHARLES F. BUENTE, a citizen -of the United States, and residing at Avalon, in the county of Allegheny and State of Pennsylvania, have invented a new and useful improvement in Pipe-Joints, of which the following as a full, clear, and exact description, reference being had to the accompanying drawings, forming part ofv this specification.

The present invention relates broadly to pipe joints and more particularly to joints of this character adapted for use in connecting comparatively large sections of cast or molded mains, such as concrete, although its use in this respect is not restricted'.

The principal object of the present invention is to provide a joint or packing of the slip type, so that adjacent sections of a main or conduit may be readily connected.

A further object of the present invention is to provide a slip joint which will readily permit expansion and contraction of the sections of the main or conduit with which it is associated.

Still another object of the present invention is to provide a joint packing of the character described which is durable, and which may be easily combined with the sections of the main with which it is to be used.

The foregoing and other objects, together with their attendant advantages, will be apparent from the accompanying specification and drawings forming a part thereof, it being premised, however, that changes may be made in the details of construction within the scope of the appended claims, without departing from the spirit of the invention.

Tn the drawings throughout the several views of which like characters of references have been used to designate like parts:

Figure l is a longitudinal section through a main provided with my improved joint;

Fig. 2 is an enlarged sectional detail view of the construction illustrated in Fig. l before the adjacent sections of the main are forced into final position; and

Fig. 3 is an enlarged detail in section of the construction illustrated in Fig. l.

Referring more particularly to the drawe ings, I have illustrated a main or conduit 1 composed of adjacent sections 2 and 3 which are here illustrated as constructed of reinforced conci'ete or like material. 'Adjacent one end, the section 2 may be provided with an enlargement 4L, in which may be formed Specification of Letters Patent.

an annular shoulder 5, as is customary in constructions of this nature.

At the time the section 2 is molded, a suitable channel member 6, formed of any desired material, may be embedded therein. This channel member is preferably provided with inclined side walls 7 forming a restricted opening for the channel member. Suitably forced into the channel member, and preferably held therein by the inturned edges formed thereon, is a sheet 8 of resilient durable material adapted to resist oxidation and corrosion, and at the same time readily conform itself to the contour of the surfaces being jointed. This sheet preferably has a width greater than the width of the channel member 6, so that in the finished .joint it projects beyond said channel member. l have found that lea-.vd may be advantageously employed for this purpose, although it will be obvious that other materials may be substituted therefor as found desirable.

Filling the space between the body of the channel member and the sheet 8, is a filler of fibrous material 9. This material forms a backing for the sheet 8 tending at all times to maintain the same outwardly away from the channel member, but permitting the same to be compressed inwardly when adjacent sections of the main or conduit are forced into position.

l have illustrated the section 3 of the main as provided with an annular-'shoulder l0 adjacent the end adapted to coperate with the section 2, and having its inner end tapered as indicated at l1 to permit easy insertion of the same within the section 2. As the sections are slid into final position, the sheet 8 is distorted, as indicated more particularly in Fig. 3, by compressing the fibrous filler aswell as the body of the material `8.

It will be apparent that expansion and contraction of adjacent sections is,permitted by the type of packing shown, and that a tight joint is made at all times due to the nature of the material employed.

The inturned edges of the channel member 7 not only provide a securing means for the material 8, but they form an interlock with the body of material of which the sections are composed so that the channel member is securely held in position.

I claim:

1.A joint for pipes, comprising a channel member secured to one of the pipe sections, a packing member carried thereby and projecting beyond sald' channel inemn ber, said packing member being adapted to coperate with an adjacent pipe section, substantially as described.

2. A joint for, pipes, comprising a channel member secured inone of the pipe sections, and a -jiieldable metallic packing member carried thereby and projecting beyond said channel member,- said packing member being adapted to coperate with an adjacent pipe section, substantially as described.

3. A joint for pipes, comprising a channel member having inturned edges secured in one of the pipe sections, and a yieldable packing .member carried thereby and projecting beyond said channel member, said packing member being adapted to conform to anadjacent pipe section, substantially as described.

Lernen 4. A joint for pipes, comprising a channel member secured to one of the pipe sections, a packing member carried thereby and projecting beyond Vsaid channel member said packmg member being adapted to coperate with an adjacent pipe section, and a filling material between said members, substantially as described.'

. 5. A joint for pipes, comprising a channel member secured to one of the pipe sections and having undercut Walls and a sheet of packing material of greater Width than the channel-Way in said member having its opposite edges held therein, said packing member being adapted to conform to an adjacent pipe section, substantially as described.

In testimony whereof I my hand.
